Bill Gates Tells Us That His One Wish Would Be Getting To Zero Carbon Emisisons

This is a link to a TED talk by Bill Gates on what can be done to solve two of our energy problems. One problem is the high cost of energy. The high cost is a real hardship for the poorest 2 billion on the planet. The other problem is global warming. That will create many problems, but it will also create hardships for the poorest 2 billion. They will starve to death because of the impact on their food production. He argues that we need to get carbon emissions down to zero because temperatures will otherwise continue to rise. He then discusses some of the ways to get to zero carbon. Since currently we emit 5 tons of carbon per person worldwide, and 20 tons per person in the US, we need to innovate our way to zero carbon. He discusses several approaches, along with the strengths and weaknesses of each, and ends up with a proposal to do the research that would enable us to burn the wasted uranium from our current nuclear reactors. There is enough wasted uranium stored in a single location in Kentucky that would produce all of the power needed in the US for 100 years. There is enough wasted uranium available from all storage facilities to satisfy the global demand for energy forever. We can even burn the waste from the reactors that use the original wasted uranium. He thinks that it could take 20 years to develop the needed reactors and 20 years to deploy them.
